REINFORCE.

SPECIFICATION forming part of Letters Patent No. 786,749, dated April 4,1905. Application filed July 22, 19 04. Serial No, 217,687-

To all whom it may concern."

Be it known that I, JOSEPH F. FRANCIA, a subject of the King of GreatBritain, and a resident of Paris, France, have invented a new andImproved Reinforce, of which the following is a full, clear, and exactdescription.

The invention relates to reinforces such as shown anddescribed in theLetters Patent of the United States granted to me on the 16th day ofAugust, 1904:,No. 767,932.

The object of the present invention is to provide a new and improvedreinforce for sticks, poles, masts, and other articles made of wood orlike material and arranged to give the article greatstrength andrigidity to withstand heavy strains without danger of breaking orimpairingthe wooden core or theshape or strength of the article and toallow of conveniently securing the ends of the reinforcing-strips to theends of the wooden core without danger of weakening either the strips orthe core.

The invention consists of novel features and parts and combinations ofthe same, as will be more fully described hereinafter and then pointedout in the claims.

A practical embodiment of the invention is represented in theaccompanying drawings, forming a part of thisspecification, in whichsimilar characters of reference indicate corresponding parts in all theviews.

Figure 1 is a side elevation of the improvement. Fig. 2 is an enlargedlongitudinal sectional elevation of one end of the same. Fig. 3 is alike view of the other end ofthe improvement. Figs. eand 5 are end viewsof the same. Fig. 6 is a cross-section of the same on the line-6 6 ofFig. 1. Fig. 7 is a sideelevation of a modified form of the improvement.Fig. 8 is an end elevation of the same. Fig. 9 is an enlargedlongitudinal sectional elevation of one end of the modified form shownin Fig. 7. Fig. 10 is a cross-section of the same on the line 10 10 ofFig. 7 Fig. 11 is an end view of another modified form of theimprovement, and Fig. 12 is an enlarged longitudinal sectional elevationof the same.

In the arrangement shown in Figs. 1 to 63, inclusive, the core A of thearticle to be re on the. outer surface portions B and B held on the endsof the core A, so as to securely fasten the ends of the strips B inposition to properly hold sides of the core A.

1 and 2, the'strips B surface of the ferrule portions B the stripsagainst the As illustrated in Figs.

(3, and the return-bend engage the outer edge of the ferrule to then lieflat on the outer surface thereof. The other end of each strip B extendspartly under the ferrule C, and the returnbend portions B pass throughopenings in the side of the ferrule O to then extend inwardly of theferrule C.

It is understood that either of the fastenings for the strips B may beused on a single core, if desired, and the fastenings for the ends ofthe strips may be varied without deviating from the spirit of myinvention. For instance, as shown in Figs. 7, 8, 9, and 10, the ferruleO at each end of the core A is provided with an inwardly-extendingannular flange G abutting against the under face of the core A. The bentportion B of each strip B engages the'fiange C as plainly indicated inFig. 9, so as to firmly attach the strip B to the ferrule 0 and as thelatter is held against inward movement on the core A it is evident thatthe strips B are firmly fastened in place on the sideof the core A. i

The flexible strips B may be laid along the extend under the inner outersurface'of the core A, as shown in Fig.

6, or the strips may extend in longitudinal grooves, as indicated inFig. 10, so that the entire exterior surface of the core A remainsunbroken, and lateral shifting of the strips B is prevented by thestrips dinal grooves in the core A.

In the 'modified'form shown in Figs. 11 and 12 the ferrules aredispensed with, and a ring fitting the longitu- IOO veer/49 D is securedby screws E to the end face of the core A and the bent portions B of theflexible strips B engage the ring D at each end of the core, so as tosecurely fasten the strips in position on the external surface of thecore A By the arrangement described the core is greatly reinforced bythe flexible strips B, B, and B", and the ends thereof are securelyfastened in position on the core Without Weakening or otherwise injuringthe core or the strips, so that when the article is subjected to astrain it bends slightly in the direction of the strain and when thestrain is removed the strips immediately flex the core back to itsnormal position.

From the foregoing it will be seen that the flexible reinforce for thecore can be easily applied and securely fastened in place, and thereinforce is so arranged as to render the article exceedingly strong andrigid and fit to Withstand heavy strains without danger of breaking orimpairing the shape, substance, or strength of the article.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. A reinforced article of the character described,comprising; a core, flexible strips on the sides of the core, and meansengaged by portions of the strips independently of the core, forsecuring the strips in place. a

2. A, rcinforcedarticle of the character described, comprising a core,flexible strips on the sides of the core, provided at their ends withbent portions, and fastening means held on the ends of the core andengaged by the said bent portions, to fasten the strips in position onthe core.

3. A rein forced article of the character de scribed comprising a core,flexible strips on the sides of the core, provided at their ends withreturn-bend portions, and fastening devices held on the ends of the coreand engaged by the said return-bend portions, to fasten the strips inposition on the core.

at. A reinforced article of the character described, comprising a core,flexible strips on the sides of the core, and ferrules on the ends ofthe core, engaged by the ends of the said strips, to hold the latter inposition on the core.

5. A reinforced article of the character described, comprising a core,ferrules on the ends of the core, and flexible strips on the sides ofthe core, extending between the outer surface of the core and the innerfaces of the said ferrules, the strips having rcl'inrn-beinl portionsengaging the ferrules.

6. A reinforced article of the character described, comprising a corehaving longitudinal grooves, flexible strips fitting in said grooves,and fast-min s means for securing the ends of the said iiexible stripsto the. ends of the said core.

In testimony wherco f l have signed my name to this specification in thepresence of two subscribing Witnesses.
